Our Certification System

Our certification system header

At UNIFI®, makers of REPREVE®, we believe provable claims benefit everyone — from suppliers and brands to retailers and consumers.

We educate partners on the impact of our products, backed by trusted certifications.

Our proprietary FiberPrint® and U-TRUST® technologies offer verified traceability and product authentication, ensuring claims can be proven, not just stated. Because transparency builds trust, and trusted data drives meaningful change.

Our Certification System

FiberPrint

U-TRUST is powered by our unique FiberPrint tracer technology, allowing us to test fibers at any point in the supply chain — from resin to yarn to fabric — to verify the use of REPREVE.
